WorldView 1 & 2

The newest commercial high resolution imaging satellites, featuring 41 cm resolution.

WorldView-1 launched September 18, 2007 by DigitalGlobe will be the most agile satellite ever flown commercially. View WorldView-1 launch images and video.  This high-capacity, panchromatic imaging system features 41cm resolution imagery (resampled to 50 cm for non-US Government customers).  Operating at an altitude of 496 kilometres, WorldView-1 will have an average revisit time of 1.7 days and will be capable of collecting up to 750,000 square kilometres (290,000 square miles) per day of half-meter imagery.  The satellite will also be equipped with state-of-the-art geo-location accuracy capabilities and will exhibit stunning agility with rapid targeting and efficient in-track stereo collection.
